RefortifAI

DRM and IP protection for AI model weights

paidupdated Jul 13, 2026

RefortifAI is a Y Combinator P2026 batch company that provides DRM and intellectual property protection for AI models by obfuscating model weights so they only run inside a hardened runtime. It solves the critical problem of model weight protection for companies distributing custom LLMs to untrusted environments, preventing IP theft while maintaining inference performance.

RefortifAI addresses an emerging and critical security gap: protecting AI model intellectual property when models are deployed outside the developer's infrastructure. As companies invest millions training custom LLMs and specialized models, distributing those models to partners, edge devices, or customer environments creates IP theft risk. RefortifAI obfuscates model weights so they only execute within a hardened runtime environment.

The platform's approach ensures that even if model files are extracted from a deployment environment, the weights are unusable without the authorized runtime. This is particularly valuable for AI companies licensing proprietary models, defense contractors deploying classified AI systems, and enterprises distributing specialized models to partner organizations with varying trust levels.

As a Y Combinator P2026 batch company, RefortifAI is at the forefront of the emerging AI model security category. The enterprise B2B pricing reflects the high-value nature of the IP being protected. The platform targets organizations where the cost of model IP theft significantly exceeds the cost of security infrastructure.

ModelScan logo

ModelScan

Security scanner for AI model files

ModelScan by Protect AI is an open-source tool that scans machine learning model files for malicious or unsafe code before they are loaded into production. Supporting formats like Pickle, HDF5, and SavedModel, it detects hidden code execution, deserialization attacks, and supply chain threats in the AI/ML model artifact pipeline, integrating into CI/CD as a critical security gate.

Guardrails AI

Validate and structure LLM outputs with composable Guards

Guardrails AI is an open-source Python and JavaScript framework for validating and structuring LLM outputs using composable Guards built from a Hub of pre-built validators. It handles structured data extraction with Pydantic models, content safety checks including toxicity, PII detection, competitor mentions, and bias filtering, plus automatic re-prompting when validation fails. The Guardrails Hub offers dozens of validators from regex matching to hallucination detection via LLM judges.
